    Link & Sync 1990 15Hp Evinrude

    So I ran the motor on my boat and it operated very well. This is a converted 9.9Hp with a 15Hp carb and I would say that it ran much faster then any 9.9Hp I ever had on this boat. Anyway, the only problem with the motor, and it is a small one, is when I am running it and remove my hand from...

    Link & Sync 1990 15Hp Evinrude

    OK. So I decided to jerry rig my carb roller just to be able to test run this motor on my boat before I buy a new cam follower for it. In case anyone wants to do this I found 1/2" pex pipe almost perfect for the inner material to replace what was on the carb roller originally. The outer...

    Link & Sync 1990 15Hp Evinrude

    So I think I might have found the overall problem with my carb roller not syncing with the throttle cam. I think my roller might be missing an outer ring on that would allow it to come closer to the cam . When comparing the one on my motor to a picture of a new one it appears the new ones have...

    Link & Sync 1990 15Hp Evinrude

    Not sure what you are saying. Should I turn the knob at the end of the tiller handle. Is that some kind of throttle stop and will that give the throttle cam line more room to move into the center of the carb roller? Which way do I turn it? Clockwise or counter clockwise.

    Link & Sync 1990 15Hp Evinrude

    Sure. It's a 32 year old motor and the carburetor on it is not original so I suspect I am not the first one to touch it. In any case my last question is if it seems right that I can not get the line on the throttle cam to move into the middle of the carb roller by turning the twist grip...

    Link & Sync 1990 15Hp Evinrude

    That is a lot of steps. I will have to print that out and take it to the motor to figure out that preliminary stuff. The youngest motor I worked on before was a 1976 Evinrude so this one seems to have added some new stuff. The thing that baffles me on this motor is when I adjust the screw on...

    Link & Sync 1990 15Hp Evinrude

    So this motor is new to me and I don't have a manual. I am looking at the carb sync to the throttle cam and I would appreciate any advice on how to sync this up correctly. On the throttle cam there is a line of plastic at the portside of the throttle cam. I am assuming the idea is to get...

    Converted 15 Hp 1990 Evinrude

    So I acquired a new outboard and it's model number is E10RESC. The guy said he put a 15Hp carburetor on it to convert the 9.9 to a 15Hp. Would anyone here who is familiar with these models know if the only difference between the 1990 9.9Hp and 15Hp was the carburetor?

    service manual for 1975 15hp evinrude?

    LIke this, made out of wood. Metal at the top with a ground wire connected to the engine ground. Adjust the bolts for the gap you want between the bolts and the metal above it. Put the spark plug boots on the bolts. Pull the starter rope and watch to see alternating sparks. A dark room...

    service manual for 1975 15hp evinrude?

    No online manuals that I know of. Perhaps others might know. This site gives a lot of info on repairs for outboards. Indispensable for the DIY outboard mechanic. https://www.leeroysramblings.com/ As for spark. 99% of the time, if that motor has not been used in a few years, your points are...

    1974 Evinrude 25hp wont run.

    I am not sure where precisely you are on your motor problems since it appears you are fixing around 3 different motors but I can't be sure. As for the fuel pumping issues, if you are running these motors in a barrel make sure your gas tank is on a table or something held up about as high as...

    1974 Evinrude 25hp wont run.

    OK. I agree the carb cleaner is not the best substance for a 2 stroke, but with that said, you do not appear to have a fuel problem. If it was a fuel problem only you should have got some kind of response with the carb cleaner. So I would not bother looking at the carb at this point. My best...

    1974 Evinrude 25hp wont run.

    If you set the points to 0.020" and you don't have the coils swapped then your timing is fine. You say you have fuel. Have you tried spraying some gas mix directly into a cylinder or through the carb to see if you get any reaction? If you do then it is most likely a fuel problem and if you...

    76 Evinrude 15Hp

    What spark plugs are you using? Just so you know those motors (1974-1976 9.9/15HP) hate Champion spark plugs. Always use NGK B6HS or B7HS spark plugs. Also, those motors should not be used for slow trolling. They like being run at higher RPMs. The problem with them is at slow RPMs the...

    Question for "the machinist"

    Well, better late then never. I am again looking at trying to reduce the slop in my throttle control. It does appear that gear #66 does not fit up tight to gear #65 and would like to shim it but I can't see where a shim would go that would tighten up the messing. It seems to me that the #66...

    1982 15HP Evinrude dies around 2 min during fast idle

    Not sure if you are testing this motor on your boat or on a boat stand with a bucket of water, but if the motor is on a stand and the tank is on the ground, try lifting the tank a little higher in elevation and see if that helps. I would think a new fuel pump would be able to pull the fuel as...

    78 Evinrude 9.9

    I assume you are talking about the knob on the side of the motor. That one I can't say. Mine has never worked and I have never needed it. I have a 1/2" boat plug stuck in the hole where mine was supposed to be. I assumed it was just a low idle stop to ensure you don't stall the motor when...

    78 Evinrude 9.9

    Start where you are or 1.5 turns out from lightly seated. Start motor. Warm it up. Bring it to a slow idle. Turn the knob clockwise 1/8th of a turn. Let it respond to that for 10 or 15 seconds. It may idle up it may do nothing. Turn it in another 1/8th of a turn. Let it respond. If...
